The presented invention relates to a retrofit and direct replacement of conventional fluorescent lighting tubes with light emitting diode (LED) lighting devices for usage in vehicles, including mass-transit vehicles such as buses, trains, subway trains, also for lighting watercrafts, aircrafts, signage, or buildings using LEDs.
For many years the lighting of interiors of vehicles, aircraft, buildings, signage, and watercraft, and more recently the lighting of exteriors of vehicles, and signage have use the cold cathode lamp; more commonly known as the fluorescent lamp or a fluorescent system. The fluorescent lamp however has limitations on its capabilities and usages. The fluorescent lamp has disadvantages to the consumer. The disadvantages of the fluorescent lamp are the short life, easily broken, low durability, high costs of replacement, high costs of specialty lights, limited color selection, electromagnetic interference (EMI) which may be harmful to other electronic equipment. The manufacturing of fluorescent lamps and debris from replaced lamps have a high environmental risks, as the chemicals inside of a fluorescent lamp are toxic. Also the flicker effect of dying or improperly installed fluorescent lamps may be extremely harmful to individuals with certain medical conditions. The constant inconsistency of fluorescent lighting colors is often a complaint of consumers who have to replace lamps on a regular basis. A fluorescent system cannot be used effectively in extreme low or high ambient temperatures.
To attempt to avoid difficulties with fluorescent lighting, proposals have been made to use LEDs as replacements for fluorescent lighting, as for example described in U.S. Pat. No. 6,860,628 issued Mar. 1, 2005 and U.S. Pat. No. 6,583,550 issued Jun. 24, 2003. While these devices do provide some of the advantages of LEDs, there remains a need for lighting systems that can supply sufficient illumination to meet lighting requirements in vehicles, including mass-transit vehicles such as buses, trains, subway trains, also for lighting watercrafts, aircrafts, buildings and signage without excessive heat build up, while reducing the amount of lamps, wiring, ballasts, power consumption and maintenance that fluorescent systems require.
In accordance with an aspect of the invention, there is therefore provided a light emitting diode lighting device and system that can be used for illuminating the interior and/or exterior of vehicles, aircraft, watercraft, signage or buildings is provided. The system includes a voltage feedback constant current power supply circuitry and high power LEDs. The printed circuit assemblies are preferably firmly mounted onto a continuous or semi-continuous mounting channel case that also works as a heat sink. By this means, it not only increases the reliability of the LED lighting tube but also it provides sufficient heat dissipation capability for the heat generated by the LEDs. Since the operating temperature of the LEDs is controlled and stays in cool condition, it dramatically increases the LED's lifetime and efficiency. The end caps and pins of this LED lighting device are fully compatible with existing conventional fluorescent light fixtures and can directly replace those fluorescent lighting tubes in vehicles, mass-transit, watercrafts, aircrafts, signage or buildings with minimal modifications.
In further aspects of the invention, an LED lighting system has a housing forming a channel and being heat conductive and rigid, with one or both ends of the housing having electrical connectors for connection to a power source. An LED array extends along the housing within the channel, each LED in the LED array having a power rating of greater than 0.5 watt. Onboard current control circuitry for the LED array is carried by the housing, preferably within the channel, and may provide current control for individual sets of LEDs. The current control allows careful control of the forward current passing through the LED array so that it controls the brightness and heat production by the LEDs.
These and other aspects of the invention are described in the detailed description of the invention and claimed in the claims that follow.
There will now be described preferred embodiments of the invention, with reference to the drawings, by way of illustration only and not with the intention of limiting the scope of the invention, in which like numerals denote like elements and in which:
In this patent document, “comprising” means “including”. In addition, a reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present.
In
At one or both ends of the housing 102 there are provided electrical connectors 103, 105, and 106 for connection of the lighting system 10 to a power source. When LED lighting system 10 is configured as a bulb, rather than as tube, it will typically have connectors only at one end. In the embodiment of
An LED array formed of LEDs 100 extends along the housing within the channel formed by the housing 102. To provide sufficient power to provide light, particularly in an industrial or commercial environment, each LED 100 in the LED array should have a power rating of greater than 0.5 watt. The circuit boards 101 provide onboard current control circuitry for the LED array. The circuit boards 101 are carried by the housing 102 and are in electrical communication with the electrical connectors 103. 105, 106. The LEDs 100 are preferably organized in groups of LEDs, either in series, or parallel. The LEDs may be surface mounted (SMT) or through hole mounted (TH). The colour of the LEDs can be any available colour such as white, blue, green, red, yellow, amber, or orange.
The onboard current control circuitry 20 is configured to provide constant current to the LEDs 100 of the LED array 209. A polarity protection circuit 201 of conventional design safeguards against the user installing the product in the wrong polarity. Current control is provided by current control circuit 202, also of conventional design. As an example, the current control circuit 202 may be use pulse width modulation (PWM) to control the current supplied to the LEDs. The circuit 202 supplies constant, controlled, current to unit for the entire LED set 209 with information from voltage sensor 203. The voltage sensor 203 receives current information from LEDs 209 and feeds back information to the current control circuitry 202. For example, in the use of PWM, the voltage sensor 203 converts the current of LED array 209 to voltage signal and supplies the voltage signal to the current control circuit 202. The current control circuit 202 senses how much the detected voltage varies from the desired level, and by varying the pulse width or frequency, changes the current supplied to the LEDs towards the desired level. The power supply 208 may be AC or DC, although in the example shown it is DC. Current control provides constant brightness and prevents overheating. A typical pulse frequency for the current control may be 200 kHz to 4 MHz. This low voltage application shown here provides voltage for applications below about 72 volts.
The organization of the circuit boards 101 is shown in
In
In
The switching power supply circuit 30 is integrated with the LEDs 100 on each section of printed circuit board 101, so that any defect of each power supply circuits or LEDs 100 would not affect the lighting device 10 as a whole. The other circuit boards 101 of the lighting device are still active. The LED lighting device 10 can be installed in polarity or no polarity, and may have any required length. The LED lighting device 10 may use voltages from 1.5V˜240V in both DC and AC, and may fit retroactively into existing fluorescent lighting fixtures after removing or bypassing the ballast. This LED lighting device 10 can be a replacement or retrofit for all existing fluorescent lighting tubes larger than the size of T6.
Immaterial modifications may be made to the embodiments described here without departing from the invention.
